mxnn. AND coNvnYna.

Be it known that I, GEORGE E. BAn m'rn, a citizen of the United States,residing at New Castle, in thecounty of Lawrence and State ofPennsylvania, have invented certain new and useful Im rovements inMixers and Conveyers; and I d lowing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make "and use the same.

My invention relates to a mixer and conveyer especially designed formixing ingradients for making glass and for feeding them to themelting-tank, although the same apparatus may be employed for mixingconcrete and other substances.

- 'Among the objects I have in-mind are to feed the tank on a level withthe tank floor, to mix the ingredients to better advantage, to conveythem in their mixed state more expeditiously to the tank and to simplifythe construction and arrangement of the different parts generally.

Another object is to provide for simultaneously crushing and feedingcullet to the conveyer which carries the ingredients to the tank. a

The invention consists of two hoppers or receptacles arranged atopposite 'sides of the conveyer and adapted to feed material to saidconveyer at the same point, one of said hogpers being designed forholding batch an having a suitable feeding device to imsure theuninterrupted delivery thereof to the conveyer, and the other hopperbeing designed for holding cullet and provided with means for crushingthe same and forcing it toward the outlet opening to the conve er. s v iThe invention also consists in the features of construction andcombinations of devices hereinafter described and specified in theclaims. v c

In the accompanying drawings, illustrating the preferred embodiments ofmy invention: I

Figure 1 is a front elevation of the two ho pers, the shaft for drivingthe feeding an crushing devices-therein, and my preferred form ofconveyor which is also driven by said shaft and which carries theingredients to the melting-tank. Fig. 2 is a plan view also showing themelting-tank. Fig. 3

Specification 0t Letters Patent. Application Med January 12, 1910.Serial No. 587,761.

0 hereby declare the folis a vertical section on the line 00-02 of Fig.2. Flg. 4 is a sectional view on the'line y-y of Fig. 2. Fig. 5 is afront elevation similar Patented Nov. 8, 1910.

to Fig. 1 exceptthat a modified form of conveyer is illustrated, andFig. 6 is a sectional view on the line z--2 of Fig. 5.

When the two hoppers are arranged on the same level withthemelting-tank, I use a conveyer comprising a fli ht of pans, asillustrated in Figs." 1 to 4, inc usive. \Vhen said ho pers'are arrangedon a lower level or be vator or conveyor, shown in Figs.v5 and 6, isemployed.

Referring first to Figs. 1 to 4:, inclusive, 1 designates the batchhopper in the bottom of which is placed a feed screw 2 which dischargesthe batch through an opening 3 to which is fitted a sliding door orclosure .4 controlled by a hand lever 5. A downwardly inclined lip orplate 6 is arranged at the lower edge of the opening 3'and projectsover'the conveyer 7 so as to deliver the batch to the center of thelatter.

The cullet hopper 8 is equipped with a feed opening 3, closure 4,operating lever 5- and lip or plate 6, similar to those of thebatchhopper. The bottom of said cullet hopper, however, is inclinedupwardly away from its discharge opening andin this hopper there aremounted two reciprocating crnshers 9," operated by means of a crankshaft 10 and guided in suitable brackets 11. The lower faces or end ofthe crnshers are inclined to conform to the bottom of the hopper. Saidcrushers not only serve to break up irregular pieces of glass or cullet,but also force the contents of the hopper through the outlet openingwhen the closure is raised.

The feed screw 2 and'crank shaft 10 are driven by suitable means, suchas the sprocket wheels and chains 12 and 13 and j 14 and 15,respectively, from the main shaft 16, journaled'in suitable stands 17.Power may be directed to the main shaft by the belt wheel .18 or in anyother. manner. Clutches 19 and 20, respectively, are provided "forthrowing the feed screw and crank shaft in or outof driving connectionwith the main shaft. By means of these clutches, the feed screw andcrank shaft may be driven in unison, said feed screw may be driven andthe crank shaft remain staow the tank floor, the endless bucket-ele- I60 1 tomary to employ a fifth man to superintend .tionary or viceversai. The. clutches 19 and 20 are controlled by hand levers 21 and 22,respectively.

The conveyer 7 comprises a series of pans 23 secured at proper intervals,to the s rocket chain 24 so that the edges of said p ates will overlapwhen they are on one of the straight stretches of said chainr The panshave upwardly turning flanges 25 attheir edges which are also adapted tooverlap. The chain 24 is passed over a sprocket wheel 26 on the mainshaft and over a'similar sprocket wheel 27 mounted adjacent to themelting-tank28. The upper stretch of the conveyer is supported by arequired number of rollers 29, ournaled in stands 30, see Fig. 4:. Itwill be noted. that the pans are adapted to break joints in passing vatethe ingredients from saidhoppers to one of the straig veyer. Itwill'also be observed that the araround the sprocket wheels butimmediately return to position withtheir edges and flanges overlappingwhen they come back to t. stretches of the con-' rangement of thehoppers with respect to the conveyer is such that the batch and culletare delivered from, said hoppers at the same point and on to the middleportion of the conveyer. The result is that the ingredients from the twohoppers are mingled or'blended on the conveyer and are delivered in thatstate to the melting-tank wherethey are more readily fused because oftheir amalgamation. The""delivery of the ingredients to the center ofthe con-.

veyernot only aids in mixing them but also prevents them from runningover thes-ide flanges of-the pans.'

The apparatus illustrated in Figs. 5 and 6' is similar to that shown inthe other figures and just described, except that a boot 31 is placedbetween the ho pers for the delivery of the materials therei rom, and aninclined bucket conveyer or elevator 32 is substituted.

5 Heretofore, ithas been customary to employ fourmen for feeding the doghouse with 'wheelbarrows, two of. the men working together alternatelyso that the feeding may be carried on continuously. .It is also custhemelting ofthe glass in the tank. By

- advanta a crusher in the other hop using my invention, one man can doall the. necessary work connected with the feeding and superintendenceof the tank so that it results inthe saving of the salaries 'oflthe fourmen whose services are dis ensed with.

Attention is directed to the nnel shape of the batch hop r which causesthe batch togradually sett e down.-to the bottom of saidhopper as thefeed screw ejects or forces out the lower stratum. This is an'importantbecause it keeps the batch moving all the timejand prevents it fromcementing or solidifying which it has a tendency to do by reason of thelime and sand which it contains.

The construction of the conveyer and the combinationtherewith of the twohoppers adapted to deliver on to it at the same point is claimed inanother a plication filed by me on April 18, 1910, Serial No. 556,018.

I claim:

1. The combination, with a hopper having an inclined bottom and adischarge opening at the base of said incline, of a crusher arranged insaid hopper, and means to reciprocate said crusher whereb the materialis also fed by it through said discharge openmg.

2. The combination, with a hopper having an inclined bottom and adischarge opening at the base of said incline, of a crusher arranged insaid hopper and having its bo't-' tom end inclined to correspond withthe bottom of the hopper, and means to reci rocate said crusher wherebythe material is 0 fed by it through said dlscharge opening.

3. The combination, with an endless conveyer, of a shaft carrying'one ofthe wheels over which the conveyer is passed, two hoppers arranged atopposite sidesof said conveyer, a feed screw in one of said hoppers, r,means for drivin said feed screw an crusher from said s aft, and meansfor delivering material from said hoppers to the conveye 4/ Thecombination, with an endless conveyer, of a shaft carrying one of thewheels overwhich the conveyer is passed, two hoppers arranged atopposite sides of sand conveyer, a feed screwyin one of said, hopers, acrusher in'the other hopper, means or driving said feed screw andcrusherfrom said shaft, clutches for separately disconnecting said drivingmeans from theshaft, and means for delivering material from said hoppersto" the conveyer.

' In testimon whereof, in presence 0 two witnesses.
